As the demand for automotive driving safety and intelligent vehicle systems increases, the demand for automotive sensors will increase dramatically. Among all vehicle sensing components, the average annual growth rate of vehicle safety sensing components is the highest, reaching 13.7%. These indications indicate that the safety demand is still the most important driving force in the automotive industry. So we think of the vehicle sensor. The so-called vehicle sensor is the input device of the car computer system. It converts various working conditions information such as vehicle speed, temperature of various media, engine operating conditions, etc. into electricity. The signal is sent to the computer to keep the engine in optimal working order. There are many sensors for vehicles. When judging the fault of the sensor, you should not only consider the sensor itself, but should consider the entire circuit in which the fault occurs. Therefore, in the search for faults, in addition to checking the sensor, check the wiring harness, the connector and the relevant circuit between the sensor and the electronic control unit. This article refers to the address: http:// The so-called sensor, in simple terms: can feel the specified device or device that is measured and converted into a usable signal according to a certain rule, usually composed of a sensitive component and a conversion component. The sensor is a detecting device that can feel the measured Information, and can transform the detected information into a signal or other required form of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The first step in detection and automatic control. However, due to the improvement of driving safety and handling requirements, the application of these sensors gradually extends to the direction of the actuator or motor. The radar technology is the principle of applying the sensor. The radar system of the vehicle can emit radio frequency electromagnetic waves, which encounter the front Vehicles or other objects can be reflected back, and the radar chip is responsible for transmitting and receiving these RF signals and processing them through the background. The background data evaluation results determine the distance of the vehicle from other vehicles and the speed of other vehicles. Therefore, when it is predicted that a vehicle collision will occur, the seat headrest and seat belt will be ready in advance to help reduce the impact of the accident. Of course, the airbags that are basically equipped in the car are also a major application area for car safety. At present, the main driving force of global vehicle driving safety is from national government regulations, consumer awareness and automobile manufacturers themselves. Therefore, there is a growth rate of related products related to safety. These years have been able to maintain stable growth and create a booming automotive sensor market. development of. Basically, the sensor components used in automobiles are more susceptible to environmental rigors during driving, including: dust, humidity, salt, fuel additives, vibration and severe impact, so strict standards are required. In addition, temperature is also an important consideration. Usually, automotive sensing components need to withstand large ambient temperature changes and measure accuracy during the life of the component. It is required to maintain accuracy in the specification. Finally, the air flow, temperature and other sensors have a growth rate of 4.6%. Among all sensors, the position, angle, speed and oxygen sensor output remained at the highest level, from $6.2 billion in 2005 to $8.6 billion in 2010. Traditionally, the market for automotive sensors is operating in an OEM mode and usually does not need to be directly facing the consumer. Therefore, the car manufacturer and the first supplier have the right to determine the relevant sensor specifications, in other words, for the sensor. For the supplier, the car manufacturer and the first supplier are their customers. In addition, if the market is further differentiated, the market can be subdivided into three categories: system suppliers that supply sensors directly to the automotive plant, including: Denso, Delphi, SIEMENS, and Bosch; and semiconductor manufacturers, including: FREESCALE, TI, INFINEON, PHILIPS and ANALOG Devices, etc., these companies also provide sensors to OEMs and system manufacturers. In addition, manufacturers specializing in the production of sensors, including: Kavlico, Melexis, ALLEGRO, Sensonor, Ruf, HITACHI, Systron-Donner, MURATA and VTI-Hamlin, etc., these companies also provide sensors to OEMs and cooperate with system suppliers. Finally, in order to emphasize the highest level of human-to-vehicle integration, the application of sensors to maximize their effectiveness, so that the ability of both the vehicle and the driver can achieve complementary mechanisms, is no longer unilaterally controlled by people, in the future of electronic vehicles Under the premise of development, this is an idea that cannot be considered.
